Fault diagnosis and elimination of heat-conducting oil furnace
| The fault phenomenon | The cause of the problem | Elimination method |
| Temperature difference between inlet and outlet oil of heat-conducting oil furnace exceeds given value (determined by experiment and operation) |
Circulating pump oil supply decreased Overload operation The thermal oil furnace does not match the heating equipment Insulation bad Oil contains gas and steam |
Eliminate oil pump and pipeline faults Reduce to normal operation Reasonable selection of thermal oil furnace Check the insulation condition and re-insulation if necessary Continue to degas and steam |
| The air hammer sound was found in the oil pipe, and the pointer of the pressure gauge was swinging at the inlet and outlet | Add the new oil into the air, not off | Boil oil with fresh oil |
| Low level alarm for expansion tank | Pipeline system (including oil furnace) failed to timely replenish oil after oil leakage and degassing |
Eliminate system defects New oil supplement |
| The pressure difference is lower than the given value |
The circulation pump is empty The heat conducting oil contains gas High filter resistance Oil leakage in thermal oil furnace tube |
Eliminate oil pump and pipeline defects Perform cooking oil degassing Cleaning filter Check heating coil in furnace |
If the pipeline oil circulation is not smooth, the possible reason is that the thermal oil furnace filter is blocked, the thermal oil viscosity increases, the valve is not fully open, there are sundries in the tube and other reasons, can be through cleaning the thermal oil furnace filter, add or replace the thermal oil, open the thermal oil furnace valve to remove sundries in the tube and other measures to solve!
